A multivalued attribute can have more than one value associated with the entity key.
Answer:
ababababab
Explanation:
The code above is written in python and python uses indentation .So let me rephrase the code accordingly and explain what the code really do.
Note x and y is a global variable which can be used by any of the function declared. According to the question x and y are 2 and 3 respectively
The first block of code describes a function f1 without any argument but the code should return the string "ab"
def f1():
return "ab"
The second block of code defines a function f2 and returns the value of f1 multiply by x. This means you are multiplying the string "ab" by 2 which will be equals to abab
def f2():
return f1() * x
The third block of code declared a function f3 and returns the sum of f2 and product of f1 and y. using PEMDAS principle the multiplication aspect will be solved first so, ab × 3 = ababab, then we add it to f2 . ababab + abab = ababababab.
def f3():
return f2() + f1() * y
Finally, we print the function f3 value to get ababababab
print(f3())
If you run the code on your IDE like below you will get ababababab
x = 2
y = 3
def f1():
return "ab"
def f2():
return f1() * x
def f3():
return f2() + f1() * y
print(f3())
Answer:
The process of sifting through the system databases and finding the relevant data to analyze is known as data mining. In predictive data mining, the process uses algorithm-based tools to go through the database and to look at the transactions to support the prediction of future volumes of the transactions. It is the task of the analytics team. It is often used with, predictive analytics. The predictive analytics is the use of data to forecast the results
B. their fire characteristics
this should be fairly obvious
